What is cartilage lubrication?

What is cartilage lubrication?

The lubrication mechanisms of articular cartilage impart the tissue with its low friction properties. Maintenance of these tribological properties is crucial to reducing wear and ensuring healthy and functional cartilage for the lifetime of the individual.

Is there fluid in cartilage?

Articular cartilage also stores synovial fluid, a sticky, viscous fluid that lubricates and circulates nutrients to the joint. When the joint is at rest, the synovial fluid is stored in the articular cartilage much like water is stored in a sponge.

Where is fluid film lubrication used?

description. In lubrication: Fluid-film lubrication. Interposing a fluid film that completely separates sliding surfaces results in this type of lubrication. The fluid may be introduced intentionally, as the oil in the main bearings of an automobile, or unintentionally, as in the case of water between a smooth rubber…

What molecule in cartilage is dominant during boundary lubrication?

Effect of graded concentrations of hyaluronan (HA) on the boundary lubrication of articular cartilage.

Why does cartilage reduce friction?

Cartilage is a flexible connective tissue that keeps joint motion fluid by coating the surfaces of the bones in our joints and by cushioning bones against impact. This smooth, transparent, glassy type of cartilage coats the ends of the bone surfaces, reducing friction in the joints.

What is boundary lubrication?

Boundary lubrication is defined as that in which the sliding surfaces are separated by a very thin molecular film of lubricant, so that the chemical and physical natures of the surfaces and the lubricant are of major importance.

How do you increase cartilage in joints naturally?

Foods that Help Rebuild Cartilage

  1. Legumes. For optimal joint function, it is important to beat inflammation wherever possible—inflammation is the primary source of collagen and, by extension, cartilage breakdown.
  2. Oranges.
  3. Pomegranates.
  4. Green Tea.
  5. Brown Rice.
  6. Nuts.
  7. Brussel Sprouts.

Why lubrication is required?

Lubrication is a crucial element in the efficiency and life-expectancy of any rotating equipment. Lubrication reduces friction and allows moving machine parts to slide smoothly past each other. According to a study by SKF, over 50% of bearing failures are the result of improper lubrication.

Which process does not require lubrication?

Hero’s chain conveyor system is designed in such a way that the rails require no lubrication. This type of conveyor system is used, for example, by a manufacturer of springs. During the production process, the springs have to be blasted with an abrasive material.

What creates synovial fluid?

Synovial fluid is produced by the synovium and is composed of water, inorganic salts and macromolecules, hyaluronic acid, lubricin and aggrecans, which contribute to the boundary lubrication.

What reduces friction in cartilage?

Lubricin reduces friction and prevents wear and tear at the cartilage surface.
